“At launch, up to eight people will be able to join a Party Chat at a time on Xbox One," a Microsoft spokesperson told Game Informer. This mirrors what is possible on the Xbox 360 right now. With launch less than a month away for both consoles in the United States, information is starting to flow more quickly. For most titles, eight-person parties are large enough. I wonder if players will want for more with games like Battlefield 4, which supports 64. In this case, more is better, and Microsoft hasn't ruled out growing the party size.
